I. INTRODUCTION
Efficient performance of any machine tool is the
right combination of:
A. Machine matched to the work load.
B. Tooling matched to the work piece.
C. Operator trained and conscientious.
W. F. Wells provides the machine tool. Consult
a reliable blade supplier for the proper tooling,
matched to the work piece.
Operators must not use this machine without first
reading through the manuals in this binder. The
time it takes is more than made up in man hours
and machine downtime saved.
This manual, together with other manuals in this
binder, explains installation, operation and
maintenance of your W. F. Wells Model W-9
band saw machine tool. The purpose is to
thoroughly familiarize operators with proper
procedures to get the best performance and dependability
from the machine.
As soon as any machine arrives on the receiving
dock, give it a thorough visual inspection to
assure no damage occurred during transport.
Normally, if the machine crating is in good
condition, the machine is in good condition. If
the shipping crate shows damage or signs of repair,
note it on the waybill.
Uncrate and inspect the machine while the driver
is still at the dock, or refuse it.
II. INSTALLATION
Carefully consider the machine installation site.
The plant engineer must establish work flow to
and from the machine.
The machine must be level and anchored for
proper, efficient, trouble free operation.
Operators must have room to perform their job
safely.
The work area must be uncluttered and welllighted.
Maintain temperature in the machine area at a
level to provide maximum operator comfort. If it
is not, machine operators will compensate in
clothing or move about, creating a condition of
hazard.
A. Site Preparation.
See the contents page for the machine floor plan
print, and optional equipment to install with the
saw. Establish machine location in relation to
material handling work flow to the machine and
related production functions.
Model W-9 does not require a special
foundation. However, the floor under the
machine must be solid and strong enough to
support machine weight with intended work load.
The machine must be level and shimmed so the
base is resting firmly on the floor, the weight
evenly distributed to the four corners of the base
without twisting or straining the saw head
columns or bed.
B. Machine Assembly.
Depending on accessories ordered, this machine
ships as a complete unit, ready to install and run.
The only assembly required is adding the coolant
pump and screens in the coolant collection
reservoir.
1. Loosely assemble optional accessory
tables to the saw bed.
Level the saw bed first, then level the accessory
to the bed.
2. See the contents page for the machine
elevation drawing for reference in assembling
the optional work length gauge.
Insert the slot end of the bar into the hole at the
front of the saw bed under the guide arm.
Align the slot in the end of the bar with the pin on
the opposite side of the saw bed. As the bar engages
the pin, place the push arm against the
post under the saw head as shown on the print.
Last, attach the spring to the bracket as shown
in the print.
3. Assemble the coolant pump and screens
in the reservoir under the blade line.
C. Pre-operation Check-out.
Do not install a blade on this machine or operate
this machine before completing the preoperation
check-out.
1. Check fluid levels and filters described in
maintenance section IV A, page 10.
2. See maintenance section D, 20, and
connect electric service to the machine. Check
motor rotation direction after hook-up.
D. Leveling and Anchoring.
This machine must be level for precision sawing.
Unauthorized moving or bumping the machine
alters the setup causing inaccurate sawing,
making releveling necessary.
See part "A," site preparation, for proper
foundation. Use leveling shims at the end of the
base only.
2

Do not shim under sheet metal at the front or
back of the machine.
1. Raise the saw head and open the vise
jaws. Place an accurate machine level along the
saw bed between the vise jaws.
Bring the reading to level with shims under either
end of the base.
2. Move the level to the stationary vise jaw
and check for level front to back across the saw
bed.
Adjust shims front or back on both ends of the
saw base for a level reading at both vise jaws.
Do not shim under sheet metal front and back of
the machine.
3. See the contents page for optional tables
or barfeed.
4. With accessory equipment leveled to the
saw bed and fasteners tightened, check all level
readings.
Tighten anchor bolt nuts on the saw and
accessories.
5. Anchor the flange to the floor, each end of
the saw base, to prevent leveling shims from
shifting during sawing.
III. SAFETY and OPERATION
Few safety devices benefit the careless worker.
Safety is an attitude either accepted or rejected
by the operator.
A. Safety.
For the operator who abides by his local shop
safety practices add the following, applying to
this machine.
1. Lock or tag out the electric disconnect
during routine maintenance.
2. Replace guards and safety devices
removed during maintenance, before returning
the machine to service.
3. A qualified assistant operator need not be
at the controls of this machine when the regular
operator is not. Authorize other workers in the
area to shut down the machine in the event of
conditions of hazard.
4. Do not allow casual climbing or leaning on
the machine. Slippery coolant covered surfaces
are not detected until too late to prevent the slip.
5. WARNING: Blade handling can do
great bodily harm. Wear heavy protective
gloves when handling the blade for positive
control of the blade.
Never wear gloves when operating this or any
machine tool.
Guard against all other body contact with the
blade.
6. After installing the blade, keep hands
away from the blade.
7. Always wear eye protection when
operating this equipment.
C. Operator Controls.
Operators must be familiar with the features of
the machine in order to get the best performance
and dependability from the machine. Function of
the controls is self-explanatory from titles
indelibly printed on the control panel at each
switch, lever and dial.
Location of the controls near the work table, their
function and sequence, provide for maximum
operator recall and efficiency.
See page 4, Figure One, showing basic electric
and hydraulic controls, numbered to correspond
with numbered descriptions here of the function
of each control.
Actual position of controls on each machine
varies according to accessories ordered with the
machine.
1. Saw blade start control is press activated,
starting the saw blade and will not deactivate on
release.
2. Stop control is press activated, shutting
down the entire system and will not deactivate
on release.
3. Cutting head raise control is press
activated, raising the saw head and will not
deactivate on release.
4. Cutting head lower control is press
activated to lower the saw head and will not
deactivate on release.
5. Emergency stop is press activated,
shutting down the entire system. To restart the
system turn the knob clockwise and it will return
to position.
3

6. Saw head control valve lowers the blade to
the work piece.
Open the valve slightly to lower the saw head
slowly.
Open the valve all the way for rapid saw head
lowering.
When sawing narrow or round work and only one
or two saw teeth contact the work piece, open
the valve only slightly, bringing the blade into
contact with the work piece slowly.
See page 4 of the Band Saw Blade Selection
and Application Manual.
After the blade begins a kerf in the work, open
the valve and the metering valve (see no. 8
under Other Controls) takes over for more
efficient sawing.
See Other Controls no. 10 for adjusting saw
head raise height.
To limit saw head rate of descent, adjust the
valve to the rate wanted.
OTHER CONTROLS not shown on page 4 are:
Optional vise control is three position,
remaining Open, Off or Clamp and must be in
Clamp when sawing to prevent the work piece
moving with the blade, binding or breaking the
saw blade.
This control operates one of two vise types,
minimum vise travel for clamping and releasing
the work piece or full stroke vise travel.
To adjust minimum travel vise to the work piece,
turn the switch to Open, release the thumb lock
knob inside the vise handle, raise the handle and
slide the vise jaw open.
Place the work piece against the stationary vise
jaw and slide the movable vise up next to the
work piece.
Return the handle to the vise slide slot and lock
the barrel half-nut onto the vise screw with the
thumb lever lock.
Adjust the vise to the work piece with the
handwheel at the end of the saw bed, close to
the work piece.
Turn the switch to Clamp.
Full stroke procedure is holding the switch Open
or Close to clamp or release the work piece.
Manual procedure is clamping and releasing the
work piece with the handwheel. See control no.
19.
Sawing force adjustment is at the metering
valve dial on the right guide arm. The dial reads
from 30 to 120 pounds sawing force.
To increase sawing force turn the thimble down
the dial until the top of the thimble is at the proper
sawing force for the work piece.
The metering valve monitors work piece
resistance to the blade.
For more details on sawing force, see Blade
Selection Manual 900409.
Sawing force is a very important factor and must
be carefully determined. Normally a thin work
section requires a light sawing force and a wide
section greater force.
However, as the blade guides spread wider for
bigger stock, a longer distance between the
guides, the blade loses some of its rigidity, or
beam strength. On wide stock use a lighter
sawing force and use only new blades which
require less force to make a satisfactory cut.
Applying heavy force to dull blades, to penetrate
the work piece when sawing wide cross sections,
causes blade runout, a crooked cut in the work
piece.
As blades dull, replace them with a sharp blade.
Set dull blades aside for sawing small work
pieces where the shorter span between the
blade guides allows greater blade beam
strength, heavier sawing force and make cuts
within tolerance.
Blade speed control is as important as
sawing force.
Running a blade too fast for the work piece
burns the blade out prematurely.
Increased surface speed of any cutting tool
makes the cutting edge run hot. Blade metal
temperature passes critical at a given point, the
cutting edge softens and the tool fails.
See the cutting chart mounted on the saw with
recommended blade speeds for most popular
metals.
Most blade suppliers furnish a slip chart with
recommendations for their blade. Page 10 of the
Saw Blade Selection Manual offers a guide.
Change blade speed with the blade motor
running. Turn the selector handwheel on the
pulley shaft at the back of the saw until the witness
mark is at the proper blade speed reading
for the work piece.
Saw head cycle adjustment.
During production sawing of small work it is not
necessary for the saw head to raise the blade
more than enough to clear the work piece
moving under the blade for the next cut. Raise
the head higher when manually feeding to allow
more time a barfeed automatically allows.
A limit switch on the saw head contacting a collar
at the top of the left saw post controls the
distance the saw head raises.
Adjust the distance the head raises.
Position the blade just above the work with the
saw head raise and stop controls.
Loosen the thumb screw on the collar. Bring the
collar down into contact with the switch until the
5

switch clicks in.
Tighten the thumb screw.
Cycle the saw head a few times to be sure of
clearance from the work piece to the blade.
Tension the blade with the handwheel
behind the left guide arm.
Turn the handwheel tight as comfortably possible
with one hand.
Use two hands for high speed steel blades.
Do not run the blade without proper tension.
The blade will slip on the drive wheel, will not
have beam strength between the blade guides
and will not saw straight.
Too much tension causes blade metal fatigue
and premature blade failure.
Guide arm setting is important for proper
blade beam strength.
CAUTION: Serious damage results from
lowering the saw head and guide arms onto the
vise jaws, work piece or work support block.
When positioning the blade guide arm make
certain the area under both guide arms is clear.
The right guide arm and vise jaw remain at the
right side of the saw bed, next to the drive wheel.
The left guide arm and vise jaw adjust to stock
size.
Position the left guide arm close to the left vise
jaw, without touching the jaw for maximum blade
support as it saws through the work piece.
Allow a half inch space for the vise jaw to open
after the cut.
Position the guide arm. Turn the handwheel at
the top of the guide arm to release the clamp.
Slide the arm to position and tighten the
handwheel securely.
The optional work length gauge adjusts
along a bar to the cut off length required.
Measure cut length from the blade kerf to the
stop pad.
The length gauge swings up out of the way
during the cut.
The cut piece falls freely away, preventing
jamming between the blade and the stop pad
which would stall or break the blade.
Adjust the saw vise to the work piece.
Place the work against the stationary vise jaw.
Unlock the movable vise jaw handle with the
thumb lever under the handle.
Slide the vise jaw up against the work piece.
Reseat the handle and lock it onto the vise
screw.
Final vise jaw tightening is manual with the
handwheel at the end of the saw bed, or with the
optional hydraulic or air vise control on the
console.
For angle sawing up to 45° loosen bolts in the
base of the vise jaws.
Set the stationary vise jaw to the angle required
with a template or protractor. Tighten nuts in the
base of the stationary jaw to hold it in place.
Slide the movable jaw up against the stationary
jaw, self-adjusting it to the same angle as the
stationary jaw. Tighten nuts in the base of the
movable jaw and check the angle with the
protractor.
NOTE: Use caution when occasional sawing at
45° with standard vise jaws. The grip area of
standard vise jaws at 45° is much less than at
90°. Angle vise jaws with full gripping area are
available as optional equipment for more
efficient angle sawing.
C. Operating Sequence.
Do not operate this machine before studying
manuals in this binder. It is the employers
responsibility to ensure that the operator of this
machine is familiar with it's operation. Follow the
sequence closely, so it becomes automatic as
you become familiar with the machine.
Blade installation procedure is in the
maintenance section under mechanical
adjustments.
1. Turn all controls Off.
2. Tension the saw blade.
3. Engage the electric disconnect.
4. Raise the saw head.
5. Move the blade guide far left.
6. Open the vise jaw.
7. Move the work piece against the stationary
vise jaw, next to the blade, not under the blade.
8. Make machine adjustments to the work
per part "B;" clearance for the blade, guide arm,
vise, optional stop length of cut and number of
pieces count.
9. Move stock under the blade for a trim cut.
Clamp the vise jaws.
10. Adjust the sawing force.
11. Start the saw blade. Adjust blade speed
for the work piece.
6

12. Open the saw head control valve slightly,
feeding the blade into the work piece slowly.
13. Monitor the chips, thin and curled. Adjust
the sawing force accordingly.
D. Trouble Shooting.
Common band sawing problems listed here give
instructions for correcting the problem. Consider
a problem carefully. Get at the underlying cause
of a problem rather than remedy a series of side
effects.
1. Scale on the work piece.
Hot-rolled steel has a degree of mill scale. On
low carbon steel the scale does not affect sawing
rates, but the scale dulls the saw blade teeth.
Remove scale from the sawing area.
2. Hard surfaces.
Torch cutting and improper grinding some steel
creates a case-hardened shell a few
thousandths of an inch thick. Sawing through it
dulls saw blade teeth.
Saw and change blades as they dull until the
hardened area saws through is the only solution.
3. Crooked sawing.
If a new blade saws crooked, or begins to saw
straight but after several cuts starts to saw
crooked and results are worse with each cut, see
the above paragraphs, the blade selection
manual and the maintenance section on sawing
force.
4. Broken blades.
Check to see if blades are breaking at the weld.
Automatic blade welders get out of adjustment,
or an inexperienced welder operator may improperly
anneal the weld.
If this is not the problem, see the maintenance
section on sawing force and blade wheel
alignment.
5. Stripped teeth.
Improper sawing force and blade speed is the
usual cause.
See the blade selection manual, and the
maintenance section for a sawing force check.
6. Poor blade life.
Blade speed too fast for the work piece is the
usual cause of poor blade life. See paragraphs
1 and 2 in this section.
Another cause of poor blade life is improper
blade brush adjustment.
The tendency is adjusting the brush too tight to
the blade.
Adjust the brush so the surface contacts teeth of
the blade only lightly to do an effective job of
cleaning the tooth gullet without wearing the
brush or teeth excessively.
7. Erratic saw head feed.
Uncontrollable saw head feed into the work
piece is poor maintenance.
a. Defective blade welding, defective weld
grinding, blade teeth points stripped or wrong
blade for the work piece.
b. Lubrication, section IV.
c. Leveling and anchoring, sec. II.
d. Blade guide clearance, blade linkage or
metering valve, sec. IV.
e. After checking the above and erratic feed
is still a problem look for brass frame thrust
screw excessive wear.
Brass marks front and back of the left post the
saw head rides on, or brass dust at the base of
the post means the machine is not level, or
thrust screw adjustment too tight to the post.
(1) Loosen lock nuts holding the thrust
screws, front and back of the left post frame.
Remove the thrust screws.
(2) File the post contour from the face of the
screws.
(3) Turn the rear screw in first, bringing it up
to the post. Push gently on the frame to feel
contact with the post.
(4) Hold the frame with the rear screw
against the post. Turn the front screw to the
post, lightly, then back it off one-eighth turn.
One-eighth screw turn is the required .008
clearance between the post and screws.
(5) Tighten the lock nuts and check the saw
head for smooth feed.
8. Saw head stall.
If the blade comes to the work piece and starts
the cut but seems to float without sawing, check
the following malfunctions.
a. Make sure the blade is sharp, and the
proper blade for the work piece.
Too much sawing force applied to a small tooth
blade on a wide work piece fills saw tooth gullets
7

efore the blade clears the work piece to empty
the gullets.
Chips locked in the tooth gullet, still in the blade
kerf, force teeth tips up away from the cut,
making the blade float through the kerf.
Change the blade to one with fewer teeth and
larger gullets, or use less sawing force on the
small tooth blade to form smaller chips, at the
risk of heating the blade to the point of hardening
the work piece.
b. Monitor the sawing force.
Use only 30 to 50 pounds of sawing force and
use the proper blade for the work piece.
c. Look for a hydraulic line kink from the blade
guides to the control console, limiting hydraulic
fluid flow from the metering valve to the control
valve.
d. Look for dirt lodged in the blade guides,
preventing the metering valve from functioning.
Keep the guides clean.
Dirt and chips blocking the metering valve
linkage forces the metering valve closed and the
saw head will not move, or come down only
slowly.
See the maintenance section for a blade guide
inspection.
e. Check the hydraulic fluid reservoir for a
milky-white color. Water or coolant in the fluid
contaminates the entire system.
See hydraulic fluid level and sawing force in the
maintenance section.
9. Saw blade stall.
If the blade jams in the cut it is the wrong blade
for the work piece, too much sawing force for the
blade or improper blade tension.
Correct the sawing practice.
Wait five minutes and press the motor starter
reset control.
If the blade stalls with the motor running, shut
the machine down.
Free the blade from the kerf and properly tension
the blade.
Rotate the work piece a few degrees if possible
so the blade will not hang up in the same kerf.
10. All system stall.
Thermal overload protected hydraulic pump
motor shuts down the system if the motor
overheats. Let the motor cool five minutes and
press the reset control.
Also see electric maintenance section D, 20.
11. Saw head drift.
It is normal for the saw head to drift down while
sitting idle for a time. Remove all work from the
vise jaws, tools and other material from the work
bed at the end of each shift.
Unauthorized machine use or drift down, the
blade coming into contact with material left in its
path, may destroy the blade and the material.
IV. MAINTENANCE
To assure smooth running machinery and save
hours of downtime and repair costs follow inspection,
adjustment, lubrication and maintenance
outlined here.
A. Lubrication.
The lubrication chart in the back of this manual
depends on shop conditions and machine use.
Some lubricants dry out or deteriorate with time.
Check the machine as shown to preserve
machine finish, seals and performance.
1. Hydraulic fluid
Routinely check fluid levels. Lock or tag out the
electric disconnect.
Check the fluid level with the saw head lowered
and the machine turned off. Fluid standing in the
hydraulic reservoir, 1" below the top of the cover
is the proper level. Maintain the level with a
good quality 135-165 SSU light hydraulic fluid.
See the chart on page 23. Low fluid level lets air
enter the pump, causing dieseling, cavitation and
a ruined pump. Dirty hydraulic fluid usually is
because of a missing reservoir cap.
Dirt in the hydraulic fluid causes orifices to plug,
and adjustments to improve poor sawing
constantly change. If hydraulic fluid inspection
reveals dirt, or is milky-white from water or
coolant, the contamination is in all lines and
cylinders.
Break primary connections and blow out the
lines.
Drain and rinse the reservoir twice with fuel oil.
Swab out the reservoir and fill it with clean
hydraulic fluid. Activate all cycles several
minutes to flush out the machine.
Repeat the process five times, or until there is no
dirt or discoloration in the hydraulic fluid.
Consider placing a chain and lock on the filler
neck and cap.
Hydraulic fluid temperature rise over 130° is a
malfunction. Check the fluid level. Check the
fluid for proper viscosity. Check that all machine
cycles function through completion, not partly
blocked.
8

2. Ring and pinion.
Do not grease or oil the drive wheel ring or
pinion gear. Grease and oil cause dirt and chips
to cling and clog the gears.
See item 9, page 19 for ring and pinion
inspection and adjustment.
3. Variable speed drive.
Keep the variable speed drive belt and pulley
faces free of dirt and grease for longer service
life
Ṫhe motor pulley (908840) has been
permanently lubricated and no additional
lubrication is required. Cycling the drive through
the entire speed range is not required.
B. Coolant Fluids and Pump.
Caution: During machine set up and trial
running, unplug the coolant pump at the in-line
disconnect in back of the machine, or fill the
coolant reservoir.
Coolant fluid is a heat sink for the pump and it
must not operate unless submersed in coolant.
Routinely clean the coolant reservoir and pump
screens. A blocked screen stalls the pump.
A damaged screen lets chips block or enter the
pump chamber, ruining the pump in minutes.
This machine has a 13 gallon coolant reservoir
capacity. Consider coolant type and machine
use before filling the reservoir. Some fluids deteriorate
more rapidly than others.
The work piece and the blade determine
coolant/lubricant type.
There are coolant fluids and there are cutting
fluids.
Faster blade speeds require efficient coolant to
prevent saw blade overheating.
Increased tool surface speed makes the cutting
edge run hot. Without proper coolant blade
metal temperature passes critical at a given
point. Blade teeth soften and dull.
a. Straight cutting oil.
Slow blade speeds for hard metals and saw
blades that remove a large chip require more
coolant/lubricant. At these slow speeds high
lubricity straight cutting oil is popular.
Do not use straight cutting oil in this machine
unless factory labels clearly show machine
equipment includes oversize coolant pump, lines
and nozzles.
b. Water soluble oils.
Water soluble oils offer good cooling as well as
good lubrication.
Use one part oil to fifteen parts water for most
steels. Use one-to-one water and soluble oil for
tool steel sawing. This machine uses this fluid.
c. Synthetic oils.
Synthetic oils, without chemical solution, are
similar to water soluble oil capability and
dependability and used in the same manner.
Use one part oil to fifteen parts water for
aluminum sawing.
A drawback to some synthetic oils is animal fat
in the formula which deteriorates in time, and at
high temperatures, causing breakdown of the
fats, creating an unpleasant odor.
This machine uses this fluid.
d. Chemical solutions.
Some cooling/cutting fluid used in high speed
aluminum machining and free-machining alloys
contain chemical wetting agents.
The application is useful but side effects are
harmful to the work piece and the machine.
Do not use chemical coolant in this machine
unless factory labels clearly show machine
equipment includes corrosion resistant pump,
hoses, seals and paint.
C. Mechanical.
1. Blade installation.
Do not install a blade on this machine before
completing the pre-operation check-out.
See the Saw Blade Selection and Application
manual to select the proper blade for the work
piece.
For maximum feed, speed and blade life,
request a reliable blade supplier conduct test
sawing with his recommended blades on the
machine and the work piece.
WARNING: Blade handling can do great bodily
harm.
Wear heavy protective gloves for positive control
of the blade.
Never wear gloves while operating a metal
cutting band saw! Guard against all other
body contact with the blade.
Follow blade manufacturer instructions for safe,
proper unpackaging a new blade for installation.
Do not recoil a used blade. Cut it apart for
disposal.
Follow blade manufacturer instructions for
breaking in a new blade.
9

a. Raise the saw head so the guide arms
clear the vise jaws.
b. Lock or tag out the electric disconnect
switch.
c. Release blade tension.
d. Open the blade wheel guard doors.
Blade wheels rotate counterclockwise, drawing
blade teeth through the work piece from left to
right against the stationary vise.
Hold the blade in front of the wheels with teeth
pointing toward the wheels.
Teeth on the lower blade loop must angle right,
toward the stationary vise jaw and drive wheel.
If teeth on the lower loop point to the back of the
machine but angle left, toward the tension wheel,
the band is inside out. Reverse it.
Following applies to grit edge blades as well,
doubling blade life when the grit edge dulls
sawing in one direction, reverse it.
For safety, clear personnel from the area.
Loop the band over a handy guard post or trash
barrel.
Twist the band, as far around the circumference
as necessary, until the band snaps over. This
dulls toothed blades. Tell blade suppliers the
proper blade welding configuration for the
machine.
e. Again, hold the blade in front of the wheels
with teeth pointing toward the wheels and teeth
on the lower loop angling right, toward the drive
wheel.
f. Place the top of the loop over the frame
posts, into the blade guard channel and onto the
wheels.
l. Start the machine. Start the blade and run
it 30 seconds.
m. Shut down the machine.
Check that the back of the blade is close to, but
not scrubbing on the wheel flanges.
.010" to .030" clearance from the back of the
blade to the wheel flange is ideal.
Check blade tension before each saw cut.
2. Blade wheel alignment.
Wheel alignment is not part of a routine machine
setup.
Factory-aligned, inspected and tested wheels,
blade and guides require no maintenance.
Experimenting or bumping the wheels or guides
with the work piece or material handling
equipment is the usual cause of misalignment.
Routinely check the wheel flanges for wear and
be alert to audible and visual changes in
machine operation.
A high-pitched metal-to-metal scrubbing sound
coming from the wheel guard doors is the back
of the blade scrubbing on the wheel flange,
wearing the flange from the wheel before the
blade breaks.
.010" to .030". clearance is ideal.
When checking wheel alignment use only a new
blade, known to be straight. A used blade may
have a camber, making alignment results
useless.
To adjust either wheel release blade tension and
lock or tag out the electric disconnect.
a. To adjust the tension wheel, see the
contents page for the tension wheel assembly
print and Figure 2, below.
g. Place the bottom of the loop into the blade
guards and around the bottom of the wheels.
Pull the back of the band up next to the wheel
flanges.
h. Tension blade just enough to take up slack
in the band.
i. One guide at a time, take the blade firmly
each side of the guide, twist the teeth down and
bring the back edge of the blade up between the
guide rollers.
j. Check that the back of the blade is against
the wheel flanges.
Close the blade wheel guard doors.
k. Fully tension the blade.
(1) Open the tension wheel guard door. The
tension wheel mounts on a sliding plate. Locate
and loosen two lock nuts, under the wheel
10

spokes, top and bottom of the outside edge of
the slide plate.
A set screw beside each lock nut is a spacer for
the plate.
(2) See "A" Figure 2.
The blade is running too far away from the wheel
flange, the wheel rim too close to the frame plate
on the outside.
Turn both set screws clockwise, equally, ¼ turn
each, pushing the outside rim of the wheel up
away from the frame plate.
NOTE: Do not overcompensate. Turn the
screws equally ¼ turn only.
(3) Tighten the lock nuts. Close the wheel
guard doors. Tension the blade. Start the blade
and run it 30 seconds.
(4) Shut down the machine.
Check that the blade is not still running too far
away from, or scrubbing on the wheel flange.
.010" to .030" clearance is ideal.
NOTE: Do not overcompensate. Turn the
screws equally ¼ turn only.
(3) Tighten the hex screws. Close the wheel
guard doors. Tension the blade and run it 30
seconds.
(4) Shut down the machine.
Check that the blade is not still running too far
away from, or scrubbing on the wheel flange.
.010" to .030" clearance is ideal.
(5) See "B" Figure 3.
The blade is running too close to the wheel
flange, scrubbing, the wheel rim too far from the
frame plate on the outside.
Turn both set screws counterclockwise, equally,
¼ turn each, resting the outside rim of the wheel
closer to the frame plate.
NOTE: Do not overcompensate. Turn the
screws equally ¼ turn only.
(6) Tighten the hex screws.
(5) See "B" Figure 2. The blade is running too
close to the wheel flange, scrubbing, the wheel
rim high on the outside.
Turn both set screws counterclockwise, equally,
¼ turn each, resting the outside rim of the wheel
closer to the frame plate.
NOTE: Do not overcompensate. Turn the
screws equally ¼ turn only.
(6) Tighten the lock nuts. Close the wheel
guard doors. Tension the blade.
Start the blade and run it 30 seconds.
Check the clearance as in step (4).
b. To adjust the drive wheel, see the
contents page for the drive assembly print and
see Figure 3, below.
(1) Open the drive wheel guard door.
The drive wheel mounts on a plate.
Locate and loosen two hex head screws, under
the wheel spokes, top and bottom of the outside
edge of the drive wheel mount plate.
A set screw beside each hex head screw is as a
spacer for the plate.
(2) See "A" Figure 3.
The blade is running too far away from the wheel
flange, the wheel rim too close to the frame plate
on the outside. Turn both set screws clockwise,
equally, ¼ turn each, pushing the outside rim of
the wheel up away from the frame plate.
Close the wheel guard doors.
Tension the blade and run it 30 seconds.
Shut down the machine and check that the blade
is not still scrubbing, or running too far away
from the wheel flange.
.010" to .030" clearance is ideal.
3. Blade brush adjustment.
Blade brush alignment to the saw blade is
important to brush and saw teeth life. Adjust the
brush properly against the blade.
See the drive assembly print for proper brush to
blade alignment.
11

The tendency is adjusting the brush too tight to
the blade, quickly making the brush misshaped
and useless.
Adjust the brush 30° to the surface of the blade,
so the brush contacts the blade teeth only lightly
to do an effective job of cleaning teeth gullets
without abrading saw teeth or wearing the brush
excessively.
4. Blade tension adjustment.
Blade tension on this model is manual, screw
type with a handwheel behind the left blade
guide.
Turn the handwheel as tight as comfortably
possible with one hand when using carbon steel
blades.
Use two hands for high speed steel blades.
Check blade tension before machine start up.
Optional blade tension indicator witness mark is
factory set for size and type blades used in general
purpose sawing.
For maximum feed, speed and blade life request
a reliable blade supplier make test cuts on the
machine and the work piece with his recommended
blade.
Tension the blade to manufacturer specifications
with a precision tension gauge mounted on the
blade.
a. With the recommended blade installed,
before taking up tension, the supplier will mount
his gauge on the blade.
b. Tension the blade. When the blade
supplier indicates proper tension for his blade,
mark the location for sawing reference.
Scribe a new witness mark on the optional
tension indicator.
On the standard machine, mark the tension
wheel slide plate location.
If blade types change for sawing other work,
tension the new blades to manufacturer
specifications.
5. Sawing force check.
The hydraulic sawing force system measures
work piece resistance to the blade while sawing,
applying uniformly controlled force to the blade
for accurate sawing regardless of configuration,
size or type work piece. Sawing force range for
this machine is 30 to 120 pounds, dialed at the
metering valve on the guide arm. Too much or
too little sawing force results in uneven sawing or
broken blades.
With each blade change, inspect the blade
guides for chips and sludge build up as they can
prevent the blade guides and metering valve
linkage from working properly, producing other
than the sawing force dialed at the metering
valve.
Sludge in the coolant or hydraulic fluid, a malfunctioning
metering valve or linkage from the
blade to the metering valve alters the actual
force the blade applies to the work piece.
Use preventive maintenance.
Sawing force is adjusted by setting the
length the linkage from the metering valve to the
carbide backup slipper travels. This travel
should be between .030" - .040" as shown in
enclosed drawing 415460.
6. Blade guide inspection.
Routinely, or when changing blades, check that
the blade guide rollers and carbides are free
from dirt and sludge and adjusted for proper
blade clearance.
See the contents page for the blade guide print.
Normally, blade guide rollers require adjustment
only after years of wearing in. Do not allow stock
to bump, break and misalign the guides.
Following are three steps for preventive
maintenance blade guide inspection:
a. Clean and inspect the guides for blade
to roller clearance.
(1) Guide rollers are factory set .001" wider
than blade thickness for proper blade clearance.
Blade thickness .035" requires .036" roller
clearance.
See the contents page for the blade guide print.
CAUTION: Rollers adjusted too tight to the
blade prevent the metering valve from controlling
the sawing force. The blade will snake through
the rollers; inaccurate sawing and blade breaking
results.
Keep the rollers clean and free wheeling.
(2) Check roller clearance with feeler
gauges. Or assemble a new blade on the
machine, tension it, run it 30 seconds to track in.
Turn the blade off and raise the saw head. Use
a new blade to check the roller clearance. A
used blade may have a camber, making
adjustment results worthless.
(3) Force the tensioned blade down out of
the guide to check for tight or loose fit between
the rollers. Twist the blade, between the wheel
and guide, to check for blade movement
between the guide arms.
(4) If feeler gauges fit snugly between the
12

ollers, or if the tensioned blade only partly returns
when pushed down out of the rollers and
there is no blade movement between the guides
when twisted from outside the guides, problems
with sawing force are not with guide roller
clearance.
Go to item 7 for a metering valve linkage
inspection.
(5) If step (4) failed, proceed with guide roller
clearance adjustment. Raise the saw head for
convenience and remove the blade.
(6) One roller on each guide arm is not
adjustable. The companion roller adjusts on a
cam shoulder bolt. Loosen the hex lock nut, top
of the casting, to unlock the cam bolt.
(7) Under the roller, rotate the hex head cam
bolt to increase or decrease clearance between
the rollers.
Go back to step (2) and repeat the clearance
check.
(8) After the rollers have been adjusted,
position the carbides so they are snug but not
binding on the blade.
b. Horizontal guide adjustment.
(1) Use a combination square with the head
centered. Place the 90° side of the head into the
vise slide in the saw bed.
Bring the face of the stationary vise jaw to
square with the combination blade.
Make the same check on the movable vise jaw.
(2) With vise jaws aligned square to the saw
bed, move the 90° side of the square head to the
end of the combination blade.
Place the head against the stationary vise jaw
and bring the square blade up against the saw
blade to check for square.
If the saw blade is parallel to the machine bed,
square to both vise jaws, go to step c.
(3) If the saw blade is not parallel to the
machine bed and 90° to both vise jaws, discover
which guide arm (or both) is out of alignment.
See "C" pages 13 and 14.
Mount a new blade on the machine and tension
it.
On top of the guide beam, loosen one guide arm
clamp at a time.
If the tensioned blade pulls either guide
assembly in or out at the blade line with the arm
loosened, the guide is out of alignment.
(4) Adjust the guide, aligning the saw blade
parallel to the bed, square to the vise jaws.
Clamp the arm at the guide beam and see the
contents page for the blade guide print.
(5) Loosen the hex screw midway on the arm
at the top of the plate holding the guide
assembly to the arm. Loosen the hex nut
immediately under it, unlocking the assembly
plate and cam bolt.
(6) Locate the hex head cam bolt on the
opposite side of the plate from the hex lock nut.
Turn it to rotate the plate and blade into
alignment with the blade wheels, parallel to the
machine bed, square to the vise jaws.
Go back to step (3). Repeat the tensioned
blade/guide movement check.
c. Vertical blade/guide adjustment.
Adjustment to align the blade parallel to the bed
requires another adjustment to pivot the blade
perpendicular square to the bed.
(1) Place a dial indicator on the machine bed
near the guide with the indicator point contacting
the blade directly above the tooth gullet. Set the
indicator to "0."
(2) Open the saw head control valve slightly
to bring the blade slowly down across the dial
indicator contact point. If the indicator dial reads
"0" bottom to top of the blade at both guides, go
to item 7.
(3) If step (2) failed, correct the dial indicator
reading to "0" bottom to top of the blade.
Locate the adjusting screw just above the guide
rollers, as seen in the Blade Alignment Bulletin
and the blade guide print.
(4) Turn the adjusting screw to pivot the
guide roller assembly and blade perpendicular
square to the machine bed. Before turning the
adjusting screw, loosen the two 10-32 flat head
screws that hold the carbide block to the guide
arm. Failure to do so will result in damage to the
adjusting screw and\or the guide itself. See
drawing 415460.
Visually check the alignment with the
combination square during the adjustment.
Make a positive check with the dial indicator for
a "0" reading bottom to top of the blade as it
passes over the indicator tip.
7. Metering valve linkage check.
See the blade guide print 415460.
Linkage travel from the back of the blade to the
metering valve on the guide arm is .030" to
13

.040".
More than .040" travel, the linkage too short, will
not control the metering valve and could allow
saw teeth to enter between the rollers, ruining
the blade and rollers.
Less than .030" travel, the linkage too long,
holds the metering valve closed, the saw head
raised, or come down only slowly. If the sawing
force check, item 5, page 15, failed, check the
linkage travel. See the blade guide print.
Make a quick visual check.
the block of wood.
Bring the saw head down.
Read the dial indicator when the saw head
stops.
e. Linkage travel more than .040" it is too
short to close the metering valve. See Figure 4,
below.
Lengthen the stem .025". Loosen hex nut "D" on
top of the barrel stem.
Turn self-lock nut "C" on the threaded stud
counterclockwise, up out of the barrel stem, not
more than one-half turn. Check the travel.
NOTE: Loosen lock nut "D" or spring tension on
the valve changes.
f. If linkage traveled less than .030" it is too
long to let the metering valve control the sawing
force. Shorten the linkage.
Reverse step e. Turn the threaded stud down
into the barrel stem.
Repeat the linkage travel check, step d.
If the sawing force test still fails with linkage
clearance from the blade to the metering valve
properly adjusted, go to item 8.
a. Raise the saw head.
DO NOT start the blade.
.030" to .040" is about 1/32 inch.
Start the saw head coming down slowly. Use a
screw driver to pry the linkage assembly up from
the blade guide casting, forcing the metering
valve closed as if the blade was forcing the
linkage to stop the saw head from coming down.
b. If prying up on the linkage more than 1/32
stops the saw head, inspect the blade backup
roller.
Replace a roller with a track worn more than
.030". See spare parts.
c. If no wear shows on the backup roller, or
after replacing it and the sawing force check still
fails but forcing the linkage up stops the saw
head from coming down, the linkage is out of
adjustment.
d. Make a positive check. Fasten a dial
indicator to the guide arm.
Place the contact point on the back edge of the
saw blade. Set the dial to "0." Place a block of
wood under the blade next to the guide arm.
Use a piece of round stock in the tooth gullet on
8. Metering valve inspection.
If guide rollers and linkage are not the cause of
a sawing force failure, check the left guide arm.
a. See the guide arm print and adjustable
spring on the left guide.
Too much tension on the spring with the guides
close together while sawing small stock may
place too much tension on the spring. The
spring tension may be holding the blade down.
Decrease tension on the spring, acting the same
as decreasing sawing force at the metering valve
on the opposite arm.
b. Also check that the spring in the metering
valve spool is not binding in the housing or
adjusted with too much tension.
With sawing force dialed to minimum setting, the
stem must be loose fitting. See Figure 4.
Relieve tension on the metering valve spring by
loosening self-lock nut "C" until the nut only
touches the spring without placing pressure on it.
After the above two checks if the sawing force
check with the bathroom scale fails, clean the
metering valve, next step.
c. Particles flaking from hydraulic line walls,
or contaminated hydraulic fluid (and filter with
optional barfeed) lets sludge accumulate in the
metering valve. See the contents page for the
metering valve print. Remove the round head
14

screw holding the stem/connecting rod linkage to
the blade backup roller. The connecting rod stem
and spring drops out of the metering valve.
Remove the 1 3/8 inch nut at the top of the stem
holding the stem to the valve body.
d. Wash all parts in mineral spirits. Inspect the
diaphragm and Teflon needle valve for wear and
embedded dirt. Replace from spare parts as
necessary.
e. Hold a cup under the valve body. Open and
quickly close the saw head valve, flushing out
the valve body with the system hydraulic fluid.
f. Cleaning the metering valve and blade
guides, replacing worn parts from the metering
valve down to the blade backup roller and
adjusting the connecting rod linkage from the
blade to the metering valve is complete overhaul.
Properly accomplished, the overhaul brings
about proper results with the sawing force check,
item 5, page 15.
9. Ring and pinion adjustment.
Maintain drive wheel ring and pinion gear
clearance at .010".
Excessive noise and wear is improper
adjustment. Check the clearance.
Tension the saw blade.
Grasp the drive wheel spokes and turn it back
and forth looking and feeling for too much
clearance.
Adjust the clearance. Loosen the two hex head
bolts each side of the pinion.
CAUTION: Do not rotate the drive belt cam
bushing under the hex head at the right of the
pinion. Tap the lower shoulder of the pinion up
or down to close or open the clearance.
10. Variable speed belt.
The primary variable speed belt requires no
other adjustment than turning the crank to
change speeds.
The drive motor must be running to change
speeds.
Do not use sharp tools, screw driver or pry bar,
to separate the pulley faces when replacing the
variable speed belt. Use a block of wood.
Scratches or burrs on the pulley face will ruin a
new belt.
Do not adjust the final timing drive belt too tight.
Adjust the belt with a half inch flex at mid-span,
easily sliding side to side on the pinion shaft.
A belt adjusted too tight, singing, wears the belt
prematurely.
Adjust the tension. Loosen the hex head bolt,
right of the pinion gear under the drive wheel
spokes.
Loosen the belt. Rotate the cam bushing under
the bolt head with the high side of the cam either
side of top or bottom.
After adjusting belt tension, before tightening the
hex head bolt, check clearance between the ring
and pinion gears, item 9, page 19.
C. Electrical Maintenance.
WARNING: COMPLETE THE
PRE-OPERATION CHECK-OUT BEFORE
STARTING THIS MACHINE.
A qualified electrician must make electric hook
up and adjustments to this equipment.
See machine voltage, labeled on the electric
cabinet door. See the contents page for the
electric print.
1. Caution: During machine installation and
trial running, unplug the coolant pump at the
in-line disconnect at the back of the machine, or
fill the coolant reservoir.
Coolant is a heat sink for the pump and it must
not operate unless submersed in coolant. See
maintenance section B, 11 on coolant fluids.
2. At installation or any electric service
alteration to the machine, check the drive motor
rotation.
Open the drive wheel guard door and start the
saw blade. The drive wheel must rotate counterclockwise.
If it does not, press the Emergency Stop control.
Lock or tag out the electric disconnect. Reverse
service into the machine electric cabinet,
reversing drive motor and wheel rotation to
counterclockwise, the direction necessary for
sawing.
DO NOT reverse wiring at the drive motor. This
leaves the hydraulic pump reversed, ruining the
pump.
3. Manual machine functions may operate
when automatic function sequences do not.
If the machine will not function in the manual
mode, begin checking at the electric source.
Trace through fuses and switches to motor
overload starter switches.
4. Routinely check limit switch mountings for
dirt and loose fasteners which could cause a
malfunction later.
5. Optional production piece counter must
show at least "1" on the dial to close circuits to
15

the drive motor.
6. Optional blade break switch shuts down the
machine if the blade breaks or loses tension for
any reason.
The tension wheel moves over to the switch,
breaking the electric circuit.
Manually pull the tension wheel away from the
switch to close the circuit. Check that blade
length is not too long for the machine.
7. A blown fuse in the 115 volt line is probably
caused by dirt or chips inside the coolant pump.
Check that coolant pump screens are clean and
in place. If screens are not in place check for a
burned out pump or locked up pump rotor.
Unplug the coolant pump at the in-line
disconnect. Replace the fuse and run the
machine.
If the fuse holds without the pump, clean all
screens and the pump rotor to determine if the
pump can be salvaged.
8. Optional blade break switch shuts down the
drive motor if the blade breaks or loses tension
for any reason.
See the contents page for the optional equipment
drawing.
The tension wheel slides over, triggering the
switch, breaking the electric circuit to the drive
motor.
Pull the wheel away from the switch.
Make sure the blade is not too long for the
machine.
D. Parts and Service.
Most-used replacement parts are available from
factory stock with same-day shipment. Service is
available by telephone conference.
1. Parts.
For 95% insurance against downtime, the lists
show most commonly used parts. Program them
into inventory on a replace-as-used basis.
2,000 hours equals one eight hour shift working
for one year.
Account for spare parts. Enter them into
inventory with a zero stock level reordering
system to assure availability when the need
arises.
Write additional part numbers assigned for plant
systems compatibility on the lists for reference.
Shelf life for parts listed is indefinite, only so long
as packaging is intact.
Look for packaging opened for inspection,
authorized or otherwise.
Repackage and identify parts in suitable containers
to preserve usefulness when the need
arises.
Except fluids and filters, expect machine life of
those parts planned for replacement to exceed
the hours shown by as much as three times.
Variables are machine operator and original
equipment manufacturer workmanship reliability.
If a needed part is not identified, provide our
parts department with a detailed description of
the part, where it is on the machine and what it
does in operation. This is enough information for
our parts department to identify and supply the
part or provide information for what to purchase
locally.
2. Service.
Preventive maintenance is the only requirement
for many years, with expendable belts, bulbs,
filters and blade brushes replaced by maintenance
personnel. It is vital to machine life and
sawing efficiency that machine operators and
maintenance personnel read and have access to
the contents of this binder. If a sawing or
machine malfunction occurs, get at the cause of
the problem rather than remedy a series of side
effects. The index in this manual is topical,
offering a solution to common problems. If a
machine problem is not resolved by in-plant
personnel, do not hesitate to call our service
department. A factory-trained and qualified
person will resolve the malfunction on the

PREVENTIVE MAINTENANCE LUBRICATION CHART MODEL W-9 .012
The following recommendations are for nominal-clean operations. Consider shop conditions and
machine use when wiping oil on exposed areas.
Saw blade and guide lubrication depends on a properly functioning coolant distribution system.
Check the coolant pump screens often to be sure they are clean and in place. Clean the coolant
reservoir and change or filter the coolant fluid often, depending on coolant type and machine use.
NOTE: Do not add grease or oil to the drive ring or pinion gear. This causes dirt and shavings to
cling that would otherwise fall away.
The motor pulley (908840) has been permanently lubricated and no additional lubrication is
required. Cycling the drive through the entire speed range is not required.
